Frequently Asked Questions

General FAQ

Q. What is the warranty on Motorola Business Two-Way Radios?

A. Motorola Business Two-Way Radios and accessories feature a one-year over-the-counter, no-question warranty. That means at anytime during the first year after you purchase Motorola Business Two-Way Radios and any Motorola Genuine accessories, you can exchange them for new units if anything were to stop working or break. As with all warranties – certain limits and exclusions do apply. Please see the full warranty here.

Q. I have some existing Motorola radios and have added new models but the audio is scratchy and there's a lot of static when talking between the old and new radios. What is causing that?

A. Your older radios are most likely set to 25 kHz channel spacing and the new radios are set to 12.5 kHz spacing. This is due to current FCC regulations. We are currently in the middle of a transition from 25 kHz to 12.5 kHz channel spacing which allows for more frequencies to become available for use and a more efficient utilization of shared airwaves. Although your older and newer radios are set to the same frequency and privacy code, the different channel spacing causes the "static" you are hearing. Contact our office or your reseller to reprogram your older radios to 12.5 kHz channel spacing. If they are not capable of being reprogrammed to the new spacing, you may need to replace your older radios. Beginning in January 2013, 25 kHz spacing will not be available on any new radio.

Q. I see radios in the stores that claim a 25 or 30 mile range – is that possible?

A. That range is theoretically possible – if you are on a mountain top with little or no atmosphere, there is no solar activity and the magnetosphere is curving just right. In other words – on the dark side of the moon. The truth is, under the best terrestrial conditions, a hand-held radio will be able to transmit – and another hand-held radio receive the signal – to a distance of 5 to 6 miles. This is very dependent on what is in between the two radios – buildings, hills, trees and even water vapor can limit that range. The higher the frequency, the more line of sight the transmission becomes.

Q. VHF or UHF – which should I use?

A. Generally speaking - since UHF is a higher frequency (around 450 MHz) than VHF (around 150 MHz) it is more line of sight and better suited to shorter distances and for use in and around buildings. VHF, being a bit more "bendy" (less line of sight) is better suited for use outdoors with fewer obstructions. However, with current technology, the range capability difference is slight, but UHF still continues to perform better in and around concrete and steel structures.

Q. Do I need a license to use Motorola Business Two-Way Radios?

A. Yes. For the CLP, CLS, RDX and RPX repeater series, an FCC site license is required. VHF and UHF business frequencies are shared across the country – by licensing the FCC is better able to control interference (crosstalk) from neighboring radio systems. This is not a per-radio license, but a single license that covers your organization and all radios being used by you on the licensed frequencies.

The DTR and RDM series operate on license-free frequencies. The chance of interference on the DTR is extremely remote thanks to its digital technologies. However the RDM only has 5 shared frequencies to choose from and may be subject to crosstalk.

DTR Series FAQ

Q. What are the key differences between analog and digital on-site business two-way radios?

A. Analog on-site radios offer only one-to-many group communications, while digital on-site radios are capable of one-to-one as well as one-to-many. Digital radios offer enhanced capabilities due to their ability to transmit and receive data as well as voice.

Q. What band do these digital on-site radios operate on?

A. The DTR Series™ Digital On-Site two-way radios operate on the 900 MHz ISM frequency band, which does not require a FCC license.

Q. What does "ISM" stand for and what are the specific frequencies in the 900 MHz ISM Band?

A. "ISM" stands for Industrial, Scientific and Medical. The ISM band operates from 902 – 928 MHz.

Q. What other products operate in the 900 MHz ISM band?

A. Other products that use the 900 MHz band include cordless phones, paging systems, security systems, wireless phones, and other data devices.

Q. What does Frequency Hopping Spread Spectrum (FHSS) mean and what are the benefits of having it?

A. The DTR Series uses a frequency hopping, spread spectrum protocol to provide protection from other products using the band. For enhanced security, FHSS has been added with 50 non-overlapping groups. Unlike analog radios, multiple group or private communications can occur simultaneously on the same channel.

Q. Can my transmissions be picked up on a radio scanner that someone might purchase from an electronics store?

A. No, DTR Series radios utilize digital frequency-hopping spread spectrum technology that does not allow eavesdropping from consumer electronics equipment.

Q. Can I use this radio on my 900MHz trunking system?

A. No, DTR Series digital on-site radios operate on the ISM band and are not compatible with existing 900 MHz analog radios.

Q. What about radio compatibility?

A. DTR Series Digital On-Site radios are only compatible with other DTR Series radio models.

Q. Can the DTR audio accessories be used with other Motorola radios?

A. DTR Series radios can use most audio accessories compatible with RDX Series, CLS Series and XTN Series radios. Contact Astra Communications for specific compatibility information.

Q. How powerful are the DTR Series radios?

A. The DTR Digital On-Site radios deliver 1 watt of transmit power.

Q. What is the coverage for the DTR Series?

A. The DTR Series features coverage of up to 300,000 sq. ft. or 25 floors in doors (coverage will vary based on terrain and conditions).

Q. What is the battery life of the DTR410 radio?

A. The DTR410 Radio uses a rechargeable lithium-ion battery that delivers up to 14.5 hours of operation based on a 5% transmit, 5% receive, 90% standby duty cycle (Optional high capacity rechargeable battery provides up to 19 hours of battery life per full charge).

Q. What is the warranty on the DTR Series radios?

A. Each DTR Series radio is backed by a limited one-year warranty on parts and labor. Consult the User Guide CD-ROM contained within each package for details.

Q. How rugged are the DTR Series radios?

A. All DTR Series radios are designed to meet Military 810 C, D, E and F standards for shock, vibration, water, dust and temperature extremes.

Q. Does the radio have different alert tones for different types of call?

A. All Group Calls use the same alert tone. By default, Private Calls use the same alert tone as Group Calls. However, when programming the contact list you can select a unique alert tone for a Private contact from a list of 12 tones.

Q. Can I download my own alert tones into the radio?

A. No, the DTR Series radios do not support downloadable alert tones. The radio is equipped with 12 alert tones that can be assigned to different entries in the contact list while in programming mode.

Q. How long does it take to clone a radio using the cloning cable?

A. The Cloning rate is dependent upon the size of the radio's contact list, but usually occurs in only a few seconds.

Q. How many characters can I use when naming a Group or Private ID?

A. Unit ID names may be up to 20 characters, but will be abbreviated to the first 10. They can be viewed in their entirety by accessing View while in the Contact List.

Q. If I am using a DTR Series radio for my company (on-site) and the building next to me has a set as well, if we are on the same public group, can we hear each other?

A. If both sets of radios are set to the same Public Group ID, Channel, and within range they will communicate to each other.

DTR Series radios ship pre-programmed with 5 Public Groups using Group ID's 1 - 5 on Channel 1. This can be changed to another of the 100 Group IDs and 10 Channels in order to provide non-overlapping communication groups or to minimize the chance of interference. Additionally, for even greater privacy, Private Groups can be created that require radios to have a unique 11-digit Group ID in order to receive transmissions.

Q. Is the DTR410 antenna removable or replaceable?

A. The DTR410 antenna is not designed to be removed. The antenna is designed to be flexible and bend rather than break. In the event that the antenna becomes damaged, the radio should be returned for repair.

Q. Is a repeater available?

A. The in-building and multi-level coverage of the DTR Series platform is up to 20% greater than the 2W UHF XU2600, so a repeater is not necessary for most on-site applications.

Q. Is the Mini Keyboard accessory required to type Unit ID names in?

A. When a new private ID is added, the unit name defaults to the unit ID. When a new group is added, the group name defaults to "Public 6" or "Private 1", with the number incrementing as new items are added. In order to change the defaulted name (to "Security" or "Fred Smith") the mini keyboard is used.
